Professional Equipment. Engineering Standards. Owner on Every Job.
Most contractors show up with hand tools and guesswork. SKJ Builders arrives with the same equipment used on commercial sites.
CAT & Bobcat Equipment
CAT 305E2 mini-excavator and Bobcat T595 skid steer on every site — not rented weekend equipment or hand tools.
Laser-Level Precision
Every concrete pour laser-leveled to commercial tolerances — critical for epoxy coatings, pole barn floors, and workshop slabs.
4,000 PSI Minimum — Always
Air-entrained 4,000 PSI with compacted gravel base. Never the cheaper 3,000 PSI mix — because NY freeze-thaw cycles don’t forgive shortcuts.
Drainage Engineering
4” Schedule 40 perforated pipe, 3/4” washed stone, correct hydraulic gradient — systems engineered for decades of performance.
Rob Munson On-Site, Every Time
No subcontractors. No bait-and-switch crews. The owner personally runs the equipment on your project — guaranteed.
Licensed & Insured in New York
Full liability insurance and NY contractor licensing on every project across Binghamton and the Southern Tier. Fully documented on request.

What Homeowners Say
Trusted by Binghamton Homeowners
“Rob poured our 30×40 garage floor and it came out absolutely perfect. Laser-leveled, no cracks after two winters. He was on-site the whole time, answered every question I had. Best contractor experience I’ve had in 20 years of homeownership.”
“We had serious water in our basement every spring. Rob came out, assessed the whole yard, and installed a French drain system that solved it completely. First spring after — completely dry. The man knows drainage better than anyone I’ve talked to.”
“SKJ Builders built our Trex deck and did the excavation for our addition. Two separate projects, both came out exactly as promised, on time, on budget. Rob is the only contractor we’ll call for anything heavy going forward. Honest, skilled, professional.”
